A "Liked" comment on a SharePoint Online Newsfeed isn't tracked in the list of comments in My Site Newsfeed

PROBLEM

On a site collection or subsite in SharePoint Online, you click Like for an entry on the Newsfeed for the site.

You browse to the My Site Newsfeed.

When you click the ellipsis button (...) on the Newsfeed page and then click Likes, the comment that you liked in the Newsfeed on the site collection or subsite is missing.

MORE INFORMATION

This behavior is by design. The comments that are displayed when you click Like in the Newsfeed display any comments that you liked from inside the My Site Newsfeed, but not from sites or site collections.
